A novel technique for the endoscopic treatment of complete biliary anastomosis obstructions after liver transplantation: through-the-scope magnetic compression anastomosis

Magnetic compression anastomosis for biliojejunostomy and pancreaticojejunostomy in Whipple's procedure: An initial clinical study

“…Tight compression by a pair of magnets causes ischemia, necrosis and exfoliation of the interposed tissue, and simultaneous remodeling of the surrounding tissues, which finally creates recanalization of the narrowed lumen or a new anastomosis. 11,12,[19][20][21][22][23][24] Of note, the compressive force between the two magnets increases continuously as the interposed tissue gets thinner and thinner. [26][27][28] Therefore, such tight compression of the two magnets largely reduces the risk of anastomotic leakage.…”

“…Magnetic anastomosis has been attempted in continuous connection between bowel and bowel, [10][11][12] vessels and vessels, [13][14][15] biliary and gastrointestinal tracts, [16][17][18] as well as in recanalization of the biliary stricture, [19][20][21][22][23][24] and bilioenteric anastomotic stricture. 12,14 Because of the encouraging and broad perspective of magnetic anastomosis in clinical medicine, a new word "magnamosis" has been recommended by Dr Michael Harrison, one of the leading scientists in this field.…”

Asia-Pacific consensus guidelines for endoscopic management of benign biliary strictures

“…Other novel techniques, such as magnetic compression anastomosis, have been developed as rescue methods, which appeared effective and safe in case reports and series. [82][83][84][85] In a recent case series by Jang et al, 83 magnetic compression anastomosis achieved biliary recanalization in 89.7% (35/39) of patients with complete postoperative or traumatic biliary obstruction. Adverse events occurred in only 1 patient with mild cholangitis, and stenosis reoccurred in 2 patients during a mean follow-up of 41.9 months.…”

“…83 A smaller magnet (2.4 mm in diameter) has been developed recently to facilitate deployment and had excellent results in treating complete post-liver transplantation BBSs. 82 Hu et al 86 applied intraductal bipolar radiofrequency ablation with or without biliary stenting in 9 patients with refractory BBSs. Immediate stricture improvement was achieved in all patients without significant adverse events, and only 1 patient developed stenosis again during a median follow-up of 12.6 months.…”

New Technique for Magnetic Compression Anastomosis Without Incision for Gastrointestinal Obstruction

“…In the esophageal region, esophageal atresia in children has been successfully treated with MCA (2,3). In the hepatobiliary region, an MCA was successfully performed for severe biliary stenosis and complete biliary obstruction that are difficult to manage using conventional nonsurgical interventions (4)(5)(6). However, its application in the gastrointestinal region is still being developed.…”
